cell | the basic/smallest unit of structure, function and organization in an organism (The second part of the "Cell Theory".) |
unicellular | a one/single celled organism |
multicellular | an organism made of many cells |
stimulus | a change in an organism's surroundings that cause it to react |
response | an action or change in behavior that occurs as a result of a stimulus |
growth | the process of becoming larger; the addition of mass (cells) to an organism |
development | the natural changes that take place during an organism's life-cycle which produce a more complex organism |
reproduce | to produce offspring that are similar to the parent(s); to make more of the same kind of organism |
scientific theory | an explanation of the natural world that is confirmed/proven with the scientific method--> observation & experimentation |

six | How many CLT are there? _____ |
three | How many parts/statements are there in the "Cell Theory"? _____ |
seven | In class, we listed how many "Cell History" scientists? _____ |
two | In class, we have compound microscopes which means they are made with _____ convex lenses. |
fine | Because the objects we view under a microscope are 3-D, we must focus back and forth with the _____ focus knob while viewing on medium and high powers. |
upside | As a result of a compound microscope using two convex lenses, the image we see is _____ down. |

The third part of the "Cell Theory" | ALL cells come from existing cells. |
Hooke | While looking through a microscope, this English scientist saw "little rooms" (boxes) when looking at cork and was the first person to call them CELLS. |
Leeuwenhoek | This Dutch scientist built high-quality lenses/microscopes and was the first person to see living cells (protists, bacteria, red blood cells, etc.). |
hundred | If the eyepiece lens is 10x and the medium power lens is 10x, the total magnification is one _____x. (HINT: multiply the two numbers) |
